Snowfall totals are alarming. In the Sierra Nevada, authorities expect between 1 to 2 feet of snow at elevations above 6,000 feet, with the highest peaks possibly receiving up to 4 feet. Wind gusts could reach between 50 to 70 mph — even hitting 80 mph in exposed areas. This kind of weather isn’t just inconvenient; it’s dangerous.

Interstate 80 over Donner Pass is particularly vulnerable to closures due to the severe conditions. Travel advisories have been issued, urging people to postpone non-essential travel until at least Tuesday. The storm isn’t limited to California; it’s expected to move eastward into Nevada, Colorado, and New Mexico after impacting California.

Key snowfall predictions:

• 1 to 2 feet of snow expected above elevations of 6,000 feet in Sierra Nevada
• Up to 4 feet of snow at the highest peaks
• Wind gusts reaching up to 80 mph in exposed areas

The situation is compounded by a winter storm watch for specific mountain regions of Wyoming. Forecasts predict heavy snow accumulation there as well—between 4 to 10 inches, with some areas above 9,000 feet seeing up to 16 inches. This unpredictable weather reminds everyone that winter storms can occur even in May.

Officials are stressing the importance of being prepared. “If you absolutely must travel during a winter storm,” they advise, “check out this list of emergency items to keep in your car so you’re prepared ahead of time.” With conditions worsening, communities are urged to stock up on emergency supplies.
